How much heat energy is needed to heat 200.0 g of water from 10.0 degrees C to 50.0 degrees C, with 4.184 J/g degreesC

Answer 1

Heat needed to heat water = mass of water x specific heat capacity water x change in temperature

Heat absorbed (or needed) = 200.0 g x 4.184 J/g. ^oC x (50.0-10.0)^oC

= 33472 J
